Description

Technical Field

[0002] Electric motors have a wide range of applications in various fields, such as in new energy vehicles in the transportation sector and in various equipment and machinery in the industrial production sector.

[0003] The stator and rotor of an electric motor are its core components. The stator, rotor, and the entire motor typically require short- or long-distance transportation during production; therefore, packaging the stator, rotor, and the entire motor is an indispensable step in the manufacturing process.

[0004] Stator and rotor components are typically packaged using standardized packaging structures. This means that a single type of packaging material is suitable for a specific stator or rotor model, making it incompatible across stators, rotors, and the entire motor. This results in high development costs and long development times for stator, rotor, and motor packaging materials. Furthermore, with continuously increasing demands for motor performance, the iteration speed of stators and rotors is accelerating, leading to more product variations and further increasing the development costs of their packaging materials.

[0053] The purpose of this invention is to provide a packaging structure for electric motors that can be used for packaging stators and rotors of various specifications of electric motors, thereby achieving packaging material sharing, which helps to shorten the R&D cycle of packaging materials and reduce the total packaging cost.

[0054] To make the objectives, advantages, and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the objectives of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar parts.

[0055] Figure 1 Schematic diagrams are shown of packaging structures for motors provided in some embodiments of the present invention. For example... Figure 1 As shown, the packaging structure includes a packing layer assembly (not labeled in the figure), support legs 20, an adapter assembly 30, and a positioning assembly 40. The packing layer assembly includes components along a first direction (e.g., ...). Figure 1 Multiple packaging layers 11 are stacked (as shown by the bidirectional arrow S1 in the figure). The support feet 20 support adjacent packaging layers 11 along the first direction, forming a packaging space (not shown in the figure) between adjacent packaging layers 11. The adapter assembly 30 is disposed within the packaging space and includes a first adapter 31 and a second adapter 32. The first adapter 31 and the second adapter 32 are respectively disposed on opposite surfaces of adjacent packaging layers 31. The first adapter 31 is provided with multiple first engagement holes 311 (e.g., ...). Figure 2 , Figure 3 and Figure 4 As shown), the second adapter 32 is provided with a plurality of second engagement holes 321 (as shown). Figure 11 (As shown). The positioning component 40 is also disposed within the packaging space and includes a first positioning member 41 and a second positioning member 42. The first positioning member 41 is selectively and detachably disposed via a portion of the first engagement hole 311 on the side of the first adapter 31 facing the second adapter 32, and the second positioning member 42 is selectively and detachably disposed via a portion of the second engagement hole 321 on the side of the second adapter 32 facing the first adapter 31.

[0056] The packaging structure is used to package motor components, including a stator 100 or a rotor 200. Each type of positioning component 40 is adapted to at least one type of component and can limit the position of the corresponding component. In actual operation, the operator selects appropriate first positioning components 41 and second positioning components 42 according to the type, specification, and packaging posture of the components to be packaged. The first positioning components 41 are connected to the first adapter 31 through an appropriate number and position of first engagement holes 311, and the second positioning components 42 are connected to the second adapter 32 through an appropriate number and position of second engagement holes 321, so that the packaging structure can be compatible with various components. That is, the application of this packaging structure achieves a shared packaging effect for components of different specifications simply by replacing the first positioning components 41 and / or the second positioning components 42.

[0057] In a further improvement, the first adapter 31 and the second adapter 32 are detachably connected to the packaging layer 11. This allows for the replacement of the first adapter 31 and the second adapter 32 as needed, adapting to the packaging of more types of components or different packaging configurations. In this case, during the packaging process, it is preferable to first connect the first positioning member 41 to the first adapter 31 and the second positioning member 42 to the second adapter 32, then connect the first adapter 31 to the packaging layer 11, and finally connect the second adapter 32 to the packaging layer 11.

[0058] It is also easy to understand that when the first adapter 31 and the second adapter 32 are detachably connected to the packaging layer 11, the development of the packaging structure can be simplified to the development of the first adapter 31, the second adapter 32, the first positioning member 41, and the second positioning member 42. However, when the first adapter 31 and the second adapter 32 are not detachably connected to the packaging layer 11, the development of the packaging structure can be simplified to the development of only the first positioning member 41 and the second positioning member 42. This can effectively shorten the development cycle, reduce development costs, and thus reduce the total packaging cost.

[0059] In practice, the first direction is the vertical direction. That is, multiple packaging layers 11 are stacked vertically. Thus, the first adapter 31 is disposed on the upper surface of the lower packaging layer 11 of two adjacent packaging layers 11, the second adapter 32 is disposed on the lower surface of the upper packaging layer 11 of two adjacent packaging layers 11, the first positioning member 41 is disposed on the upper surface of the lower adapter, and the second positioning member 42 is disposed on the lower surface of the upper adapter. For ease of description, the following description will be based on the first direction being vertical, and the first adapter 31 will be referred to as the lower adapter, the second adapter 32 as the upper adapter, the first positioning member 41 as the lower positioning member, and the second positioning member 42 as the upper positioning member.

[0060] It should be understood that the number of each of the adapter group 30 and the positioning group 40 is at least one. When the number of the adapter group 30 and the positioning group 40 is multiple, each positioning group 40 corresponds to one adapter group 30, such that the first positioning element 41 of each positioning group 40 is disposed on the first adapter 31 of the corresponding adapter group 30, and the second positioning element 42 of each positioning group 40 is disposed on the second adapter 32 of the corresponding adapter group.

[0061] Figure 2 and Figure 3 A schematic diagram of an alternative structure for the lower adapter is shown, referred to as the first lower adapter 31a. (As shown) Figure 2 and Figure 3 As shown, the first lower adapter 31a is provided with a plurality of first engagement hole groups (not labeled in the figure), which are arranged at intervals along a second direction. Each first engagement hole group includes a plurality of first engagement holes 311, and the plurality of first engagement holes 311 in the same first engagement hole group are arranged at intervals along a third direction. Both the third direction and the second direction are horizontal, and the second direction is perpendicular to the third direction. In the figure, the second direction is identified by a double-headed arrow S2, and the third direction is identified by a double-headed arrow S3.

[0062] Figure 6 A schematic diagram of the structure of the lower positioning member that matches the first lower adapter 31a is shown. This lower positioning member 41 is referred to as the first lower positioning member 41a. Figure 7 This diagram illustrates the assembly of the first lower fixing member 41a and the first lower adapter member 31a, which limits the movement of the rotor. Figure 6 and Figure 7As shown, each positioning element group 40 includes two first lower positioning elements 41a. The two first lower positioning elements 41a of the same positioning element group 40 are arranged at intervals along the second direction, and each first lower positioning element 41a is selectively detachably connected to the first lower adapter 31a through a portion of the first engagement hole group. The two first lower positioning elements 41a define a first cavity (not shown in the figure), the axis of the first cavity extends along the second direction, and the cross-section of the first cavity at the first lower positioning element 41a perpendicular to the second direction is a semi-circular arc or a minor arc.

[0063] Specifically, each of the first lower positioning members 41a includes a first segment 411, a second segment 412, and a third segment 413 arranged sequentially and interconnected along a direction away from the other first lower positioning member 41a. The surface of the first segment 411 at the end away from the first lower adapter 31a forms at least a first arcuate surface 4111, the surface of the second segment 412 at the end away from the first lower adapter 31a forms at least a second arcuate surface 4121, and the surface of the third segment 413 at the end away from the first lower adapter 31a forms at least a third arcuate surface 4131. The third arc surface 4131, the second arc surface 4121, and the first arc surface 4111 are coaxial, and the axes of the third arc surface 4131, the second arc surface 4121, and the first arc surface 4111 extend along the second direction. The diameter of the third arc surface 4131 is larger than the diameter of the first arc surface 4111, and the diameter of the second arc surface 4121 is not smaller than the diameter of the first arc surface 4111. The first cavity is formed between the third segments 413 of the two first lower positioning members 41a, and is located on the side of the first arc surface 4111 and the second arc surface 4121 away from the first lower adapter 31a. The axial dimension of the first cavity is determined by the distance between the two first lower positioning members 41a.

[0064] Those skilled in the art will understand that the stator 100 includes a stator core 110 and a winding 120, wherein the winding 120 protrudes from the end face of the stator core 110 at both axial ends of the stator 100. The rotor 200 includes a rotor core 210 and a central shaft 220, wherein the central shaft 220 protrudes from the end face of the rotor core 210 at both axial ends.

[0065] like Figure 7As shown, when the component to be packaged is the rotor 200, the rotor core 210 is housed in the first cavity, and the axis of the rotor 200 extends in the horizontal direction, such that the outer peripheral surface of the rotor core 210 abuts against the first arc surface 4111, the end face of the rotor core 210 abuts against the surface of the third segment 413 near the first segment 411, and the portion of the central shaft 220 protruding from the end face of the rotor core passes through the arc groove defined by the third arc surface 4131 into the first cavity.

[0066] When the component to be packaged is the stator, the stator core is housed in the first cavity, and the axis of the stator extends horizontally, such that the outer peripheral surface of the stator core abuts against the first arc surface, the end face of the stator core abuts against the surface of the third segment near the first segment, and the portion of the central shaft protruding from the end face of the rotor core passes through the first cavity from the semi-circular groove defined by the third arc surface (not shown in the figure).

[0067] That is, the first lower adapter 31a and the first lower positioning member 41a are suitable for the packaging posture when the parts are placed horizontally, and only the distance between the two first lower positioning members 41a needs to be adjusted to adapt to parts with different axial dimensions.

[0068] Generally, such as Figure 6 As shown, the first lower positioning member 41a is provided with two third engagement holes 414, which are spaced apart in the third direction. Correspondingly, each group of first engagement holes includes two first engagement holes 311. Thus, depending on the axial dimension of the component to be packaged, each first lower positioning member 41a is connected to the first lower adapter 31a through the first engagement hole 311 of one group of first engagement holes.

[0069] In an optional example, the first lower positioning member 41a includes a base and a connecting portion 415. The base includes a first segment 411, a second segment 412, and a third segment 413. There are two connecting portions 415, located at opposite ends of the base in the second direction. Each connecting portion 415 has a third engaging hole 414.

[0070] Optionally, the lower surface of the base protrudes beyond the lower surface of the joint 415. Accordingly, as... Figure 2 and Figure 3As shown, a clearance groove 312 is formed on the upper surface of the first lower adapter 31a. The clearance groove 312 is located between two first engagement holes 311 in the same first engagement hole group to accommodate the portion of the base protruding from the lower surface of the engagement portion 415.

[0071] It is easy to understand that when there are multiple adapter groups 30 and multiple positioning groups 40, the total number of first lower positioning elements 41a included in the packaging structure is greater than or equal to n+1 and less than or equal to 2n, where n represents the number of positioning groups 40, and its value is a positive integer greater than 2. Specifically, when multiple positioning groups 40 are distributed, the packaging structure includes 2n first lower positioning elements 41a. When at least two of the multiple positioning groups 40 are continuously arranged along the second direction such that adjacent two positioning groups 40 share one first lower positioning element 41a, the number of first lower positioning elements 41a included in the packaging structure is greater than or equal to n+1 and less than 2n. For example, when the packaging structure includes two positioning groups 40, and the two positioning groups 40 are continuously arranged along the second direction and share one first lower positioning element 41a, the packaging structure includes three first lower positioning elements 41a; or, for example, the packaging structure includes three positioning groups 40, namely a first positioning group, a second positioning group, and a third positioning group. In a positioning component group, the first positioning component group and the second positioning component group are continuously arranged along the second direction and share a first lower positioning component 41a. When the third positioning component group is arranged alternately with the first positioning component group and the second positioning component group, the packaging structure includes five first lower positioning components 41a. Alternatively, the packaging structure includes four positioning component groups 40, wherein two positioning component groups 40 are continuously arranged along the second direction and share a first lower positioning component 41a, and the other two positioning component groups 40 are continuously arranged along the second direction and share a first lower positioning component 41a. In this case, the packaging structure includes six first lower positioning components 41a.

[0072] Figure 4 and Figure 5 An alternative configuration of the lower adapter is shown, referred to as the second lower adapter 31b. (See diagram below.) Figure 4 and Figure 5 As shown, a plurality of the first engagement holes 311 are arranged at intervals around a preset axis extending in a vertical direction and distributed on different circumferences with the preset axis as the axis.

[0073] In a specific example, a portion of the plurality of first engagement holes 311 are distributed on a second circumference with the predetermined axis as its axis, and another portion of the plurality of first engagement holes 311 are distributed on a third circumference coaxial with the second circumference. The diameter of the third circumference is different from the diameter of the second circumference; for example, the diameter of the third circumference is larger than the diameter of the second circumference. For example, as... Figure 5 As shown, there are 20 first engagement holes 311. These 20 holes are sequentially labeled a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t along the direction surrounding the preset axis. The holes labeled a, b, c, e, g, h, o, p, q, r, s, t are further specified. The first joint hole 311, marked as l, n, o, p, r, and t, are spaced apart on the second circumference; the first joint hole 311 marked as f, k, m, q, and s are spaced apart on the third circumference. Furthermore, the plurality of first joint holes 311 located on the second circumference can be arranged at least partially equal intervals or at least partially unequal intervals; the embodiments of the present invention do not limit this arrangement.

[0074] Optionally, a positioning groove 313 with a circular cross-section about the preset axis is provided on the upper surface of the second lower adapter 31b. All the first engagement holes 311 are located on the outer periphery of the positioning groove 313.

[0075] Figure 8 A schematic diagram of the lower positioning member adapted to the second lower adapter 31b is shown, referred to as the second lower positioning member 41b. Figure 8As shown, the second lower positioning member 41b includes a plurality of sub-positioning members 416, which are arranged sequentially around the preset axis and define a second cavity 417, the second cavity 417 having a circular cross-section. Each sub-positioning member 416 is selectively and detachably connected to the second lower adapter 31b through a portion of the first engagement hole 311. It can be understood that the cross-section of the second cavity 417 refers to the section of the second cavity 417 perpendicular to the vertical direction.

[0076] More specifically, such as Figure 9 and Figure 10 As shown, each of the sub-positioning members 416 specifically includes a fourth segment 4161, a fifth segment 4162, and a sixth segment 4163 arranged sequentially and interconnected in an upward direction (i.e., away from the second lower adapter 31b). The second cavity 417 extends from the fourth segment 4161 to the sixth segment 4163, and the diameter of the second cavity 417 at the fourth segment 4161 is smaller than its diameter at the sixth segment 4163, and the diameter of the second cavity 417 at the fifth segment 4162 is not smaller than its diameter at the sixth segment 4163, so that a stepped surface 4164 is formed at the intersection of the fifth segment 4162 and the fourth segment 4161.

[0077] When the component to be packaged is the stator 100, such as Figure 10 As shown, the stator 100 is partially placed into the second cavity 417, such that the axis of the stator 100 extends in the vertical direction. Thus, the lower end face of the stator core 110 abuts against the stepped surface 4164, the outer peripheral surface of the stator core 100 abuts against the inner peripheral surface of the sixth segment 4163, and the portion of the winding 120 protruding from the lower end face of the stator core 110 is accommodated in the portion of the second cavity 417 located at the fourth segment 4161.

[0078] When the component to be packaged is a rotor, the rotor is partially placed into the second cavity such that the rotor axis extends vertically, such that the lower end face of the rotor core abuts against the stepped surface, the outer peripheral surface of the rotor core abuts against the inner peripheral surface of the sixth segment, and the portion of the central shaft protruding from the lower end face of the rotor core is accommodated within the portion of the second cavity located at the fourth segment (not shown in the figure).

[0079] That is, the second lower adapter 31b and the second lower positioning member 41b are adapted to the packaging posture when the component is placed longitudinally.

[0080] It is understood that the inner surface of the fourth segment 4161 is part of a circumferential surface, and the inner surface of the sixth segment 4163 is part of another circumferential surface. By selecting second lower positioning members 41b of different specifications, components with different radial dimensions can be adapted. The diameters of the circumferential surfaces containing the inner surfaces of the fourth segment 4161 and / or the inner surfaces of the sixth segment 4163 of the sub-positioning members 416 of the second lower positioning members 41b of different specifications are different.

[0081] It can also be understood that the sub-positioning member 416 is provided with a plurality of fourth engagement holes (not shown in the figure). The arrangement of the plurality of fourth engagement holes on the sub-positioning member 416 of different specifications of the second lower positioning member 41b may be different, for example, on different circumferences, or on the same circumference but with different spacing between two adjacent fourth engagement holes. According to the specific distribution of the fourth engagement holes on the sub-positioning member 416, by selecting a suitable position of the first engagement hole 311 on the second lower adapter 31b to cooperate with it, the connection between different sub-positioning members 416 and the second lower adapter 31b can be realized.

[0082] Figure 11 This is a schematic diagram of an optional structure for the upper adapter. For example... Figure 11 As shown, the upper adapter is provided with a plurality of second engagement hole groups, each of which includes a plurality of second engagement holes 321. The plurality of second engagement holes 321 in different second engagement hole groups are arranged according to different rules.

[0083] The number of the second mating hole groups, the number of second mating holes 321 in each second mating hole group, and their arrangement rules are all set according to requirements. See also: [link to specific example]. Figure 11 The number of the second set of joint holes is five, namely the first set of the second set of joint holes, the second set of the second set of joint holes, the third set of the second set of joint holes, the fourth set of the second set of joint holes, and the fifth set of the second set of joint holes. For ease of understanding, Figure 11 The second joint holes 321 of different second joint hole groups are identified by different colors. Specifically, the second joint holes 321 of the first second joint hole group are shown in red, the second joint holes 321 of the second second joint hole group are shown in green, the second joint holes 321 of the third second joint hole group are shown in blue, the second joint holes 321 of the fourth second joint hole group are shown in purple, and the second joint holes 321 of the fifth second joint hole group are shown in gray.

[0084] The first second engagement hole group includes two sub-engagement hole groups, which are spaced apart and symmetrically arranged along the third direction. Each sub-engagement hole group includes a plurality of second engagement holes 321, which are spaced apart along the second direction.

[0085] The second second engagement hole group has a plurality of second engagement holes 321 arranged along the first circumference and symmetrically distributed on opposite sides of the first second engagement hole group in the third direction. Optionally, the second second engagement hole group includes six second engagement holes 321.

[0086] The third second engagement hole group includes four second engagement holes 321. In the third second engagement hole group, the four second engagement holes 321 are located between the two sub-engagement hole groups and are respectively arranged at the four vertices of a rectangle. One of two adjacent sides of the rectangle extends along the second direction and the other extends along the third direction.

[0087] The fourth second engagement hole group includes two second engagement holes 321. In the fourth second engagement hole group, the two second engagement holes 321 are arranged at intervals along the second direction, and the line connecting the centers of the two second engagement holes 321 can be the axis of symmetry of the two sub-engagement hole groups, and the two second engagement holes 321 are located on opposite sides of the rectangle containing the four second engagement holes 321 of the third second engagement hole group in the second direction.

[0088] The fifth second engagement hole group is located on one side of the first second engagement hole group in the second direction. The fifth second engagement hole group includes two second engagement holes, and the two second engagement holes 321 of the fifth second engagement hole group are spaced apart along the third direction.

[0089] The upper positioning member corresponding to the horizontally placed component is selectively and detachably connected to the upper adapter through a portion of the second engagement holes 321 of the first second engagement hole group. There may be multiple second engagement holes 321 connected to the upper positioning member, distributed on two sub-engagement hole groups, for example, symmetrically distributed. The upper positioning member corresponding to the vertically placed component may be detachably connected to the upper adapter through one of the second, third, fourth, or fifth second engagement hole groups, depending on the actual situation. Alternatively, it may be detachably connected to the upper adapter through multiple second engagement holes 321 located in different second engagement hole groups, depending on the actual situation.

[0090] Those skilled in the art will understand that the upper positioning member cooperates with the lower positioning member to constrain the movement of the component in the first direction, thereby limiting the component in the vertical direction. The structure of the upper positioning member can be set according to actual conditions, and this embodiment of the invention does not limit it.

[0091] Please return to the reference. Figure 6 and Figure 7 In the first lower positioning member 41a, preferably, the radius of the second arc surface 4121 is larger than the radius of the first arc surface 4111. This creates a gap between the end face edge of the stator core or the rotor core and the second arc surface 4121, preventing them from contacting each other. This is because the end face edge of the stator core or the rotor core is relatively sharp. If the radius of the second arc surface 4121 were equal to the radius of the first arc surface 4111, the edge of the stator core or the rotor core would contact the second arc surface 4121, easily shearing the first lower positioning member 41a. This would cause debris to form in the first lower positioning member 41a, resulting in abnormal cleanliness of the stator core or the rotor core, and could also lead to lamination problems in the stator core or the rotor core.

[0092] Similarly, please refer to... Figure 9 and Figure 10 In the second lower positioning member 41b, the diameter of the second cavity 417 at the fifth segment 4162 is greater than its diameter at the fourth segment 4161, such that the edge of the lower end face of the stator core or the rotor core is spaced apart from the inner circumferential surface of the fifth segment 4162 without contacting it.

[0093] As previously stated, the packing layer group includes packing layers 11 stacked vertically, and under the support of the support legs 20, a packing space is formed between two adjacent packing layers 11. The number of packing spaces can be adjusted by adjusting the number of packing layers 11.

[0094] Furthermore, the height of the support leg 20 is adjustable so that the vertical dimension of the packing space can be adjusted according to the radial dimension of the horizontally placed component or the axial dimension of the vertically placed component.

[0095] In optional examples, such as Figure 12As shown, the support leg 20 is composed of multiple stacked sub-support legs 21. Specifically, each sub-support leg 21 has a positioning structure at both ends in the vertical direction for positioning when stacked. In a specific example, the lower end face of the sub-support leg 21 has a first insertion groove 211, and the upper end face of the sub-support leg 21 has a first insertion protrusion 212, so that one sub-support leg 21 can be inserted into the first insertion groove at the lower end of another sub-support leg 21 through the first insertion protrusion at its upper end. Thus, the height of the support leg 20 can be adjusted by adjusting the number of sub-support legs 21 and / or by replacing sub-support legs 21 with different heights.

[0096] The support foot 20 can also be connected to the packaging layer 11 by a plug-in connection. For example, a second plug-in protrusion 111 is formed on the upper surface of the lower packaging layer 11 (e.g., Figure 13 As shown), the second insertion protrusion 111 is inserted into the first insertion groove of the sub-support foot 21 at the lowest end of the support foot 20; a second insertion groove is formed on the lower surface of the packaging layer 11 located above, and the second insertion groove accommodates the first insertion protrusion of the sub-support foot 21 at the uppermost end of the support foot 20.

[0097] Please continue to refer to this. Figure 13 A support foot positioning groove 112 is formed on the upper surface of the packaging layer 11, and a second insertion protrusion 111 is provided on the bottom wall of the support foot positioning groove 112. Preferably, the cross-section of the support foot positioning groove 112 (i.e., the cross-section of the support foot positioning groove 112 perpendicular to the vertical direction) gradually increases from bottom to top. That is, the side wall of the support foot positioning groove 112 is formed as an inclined guide wall, so that the lower end of the support foot 20 can be inserted into the support foot positioning groove 112 under the guidance of the side wall of the support foot positioning groove 112, and the second insertion protrusion 111 is accurately inserted into the first insertion groove 211.

[0098] It is understood that in other examples, the positions of the first insertion slot and the first insertion protrusion can be interchanged, and the positions of the second insertion slot and the second insertion protrusion can be interchanged. That is, the first insertion slot is provided at the upper end of the sub-support foot, the first insertion protrusion is provided at the lower end of the sub-support foot, the second insertion slot is provided on the upper surface of the lower packaging layer, and the second insertion protrusion is provided on the lower surface of the upper packaging layer (not shown in the figure).

[0099] Generally, such as Figure 14As shown, the packaging structure also includes a base 50 and a shock absorber 60. The base 50 is supported below the packaging layer assembly, and the shock absorber 60 is disposed on the base 50.

[0100] In an optional example, the base 50 includes a tray portion 51 and a support leg 52, the support leg 52 being supported below the tray portion 51, the tray portion 51 supporting the packing layer assembly. The support leg 52 includes a first sub-support leg 521 and a second sub-support leg 522, the first sub-support leg 521 connecting the second sub-support leg 522 to the tray portion 51. A shock absorber 60 is disposed between the first sub-support leg 521 and the second sub-support leg 522.

[0101] Optionally, please return to the reference. Figure 13 At least one first clamping groove group is formed on the upper surface of the packaging layer 11. Each first clamping groove group includes two first clamping grooves 113. The two first clamping grooves 113 in the same first clamping groove group are arranged at intervals along a fourth direction and are also symmetrical about the axis of the packaging layer 11. The first clamping groove 113 has a reference groove wall 1131, which extends along a fifth direction, the fourth direction and the fifth direction being horizontal and perpendicular to the fifth direction. A clamping hole (not shown in the figure) is provided on the reference groove wall 1131. The first clamping groove group is used to cooperate with a first robot arm so that the robot arm can clamp the packaging layer 11, thereby lifting and moving the packaging layer 11. When the first robot arm clamps the packaging layer 11 through the first clamping groove group, the gripper of the first robot arm partially extends into one of the first clamping grooves 113 of the first clamping groove group and further extends into the clamping hole to achieve clamping of the packaging layer 11.

[0102] In a specific example, two sets of the first clamping grooves are formed on the upper surface of the packaging layer 11. The first clamping groove 113 of one set is referred to as a first type of first clamping groove 113a, and the first clamping groove 113 of the other set is referred to as a second type of first clamping groove 113b. Please continue to refer to... Figure 13Two first-type first clamping slots 113a are located between two second-type first clamping slots 113b. The first-type first clamping slots 113a are hexagonal in shape and have two sidewalls extending along the fifth direction, wherein the sidewall farther from the axis of the packaging layer 11 and extending along the fifth direction is designated as the reference sidewall 1131. The second-type first clamping slots 113b are quadrilateral in shape and have two sidewalls extending along the fifth direction, wherein the sidewall farther from the axis of the packaging layer 11 and extending along the fifth direction is designated as the reference sidewall 1131.

[0103] Optionally, the packaging layer 11 has two reference edges 114 that are opposite each other in a sixth direction and extend along a seventh direction, wherein the seventh direction and the sixth direction are horizontal, and the seventh direction is perpendicular to the sixth direction. A plurality of second clamping slot groups are formed on the lower surface of the packaging layer 11. These second clamping slot groups are spaced apart along the sixth direction and symmetrically arranged about a straight line extending along the seventh direction and intersecting the axis of the packaging layer 11. Each second clamping slot group includes two second clamping slots 115. Within the same second clamping slot group, the two second clamping slots 115 are spaced apart along the seventh direction, and the mutually distant ends of the two second clamping slots 115 extend to the corresponding reference edge 114 to form openings. The arrangement of the plurality of second clamping slot groups allows a second robotic arm to clamp the packaging layer 11 through at least a portion of the second clamping slots 115, thereby lifting and transporting the packaging layer 11. When the second robotic arm clamps the packaging layer 11 through the second clamping slot group, the grippers of the second robotic arm partially enter the second clamping slot 115 from the opening of the second clamping slot 115.

[0104] In an optional embodiment, the packaging layer 11 has a rectangular structure. That is, one of two adjacent edges of the packaging layer 11 extends along the sixth direction and the other extends along the seventh direction. In this case, when the first lower adapter 31a is connected to the packaging layer 11, it is preferable that the second direction is the same as the sixth direction and the third direction is the same as the seventh direction, or the second direction is the same as the seventh direction and the third direction is the same as the sixth direction. Furthermore, it is also preferable that the fourth direction is the same as the sixth direction and the fifth direction is the same as the seventh direction, or the fourth direction is the same as the seventh direction and the fifth direction is the same as the sixth direction.

[0105] Furthermore, the specific positions of the lower adapter, the support foot 20, the first clamping groove 113, and the second clamping groove 115 are not particularly limited in this embodiment of the invention, as long as the lower adapter, the support foot 20, the first clamping groove 113, and the second clamping groove 115 do not interfere with each other. In a specific example, the packaging layer 11 has a rectangular structure, and the long side of the packaging layer 11 extends along the seventh direction and the short side extends along the sixth direction. The upper surface of the packaging layer 11 is defined by the centerline L1 of the short side of the packaging layer 11 (e.g., ...). Figure 13 (As shown by the blue dashed line in the image), the two 1 / 3 dividing lines L2 on the longer side (as shown in the image). Figure 13 The packaging layer (as shown by the red dotted line) is divided into six positioning areas. Each of the lower adapters is located within one of the positioning areas. There are 10 support feet 20. The 10 support feet 20 are arranged along the four edges of the packaging layer 11 at the four corners of the packaging layer 11, at the intersection of the center line L1 of the short side and the short side, and at the intersection of the 1 / 3 dividing line L2 of the long side and the long side. There are two first clamping slot groups. The two first clamping slots 113 of the same clamping slot group are arranged at intervals along the center line L1 of the short side. There are two second clamping slot groups. The two second clamping slot groups are arranged at intervals along the long side of the packaging layer 11. Each second clamping slot 115 is located between two adjacent support feet 20.

[0106] In a preferred embodiment, the positioning area of ​​the packaging layer 11 is formed as a recess. The outer periphery of each positioning area is formed as a protrusion. The support foot positioning groove 112 and the first clamping groove 113 are both disposed on the protrusion.

[0107] In addition, such as Figure 15 As shown, the packaging structure also includes a side panel 70 and a top cover 80. The side panel 70, the top cover 80 and the base 50 enclose a box. The packaging layer assembly, the support legs 20, the adapter assembly 30 and the positioning assembly 40 serve as the main body for directly packaging the components and are placed inside the box.

[0108] While the present invention has been disclosed above, it is not limited thereto. Those skilled in the art can make various modifications and variations to the present invention without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention also intends to include such modifications and variations.
